The aim of the proposed project is to develop methods for the simulation of space utilisation. Up to now no methods for building performance evaluation are available which involve the occupants of the building. Instead, assumptions are made about people’s movement through space and their responses to the environment. These assumptions are input for important design decisions (e.g. capacity of elevators, width of corridors, escape routing) sophisticated calculations (e.g. cooling and lighting calculations) and simulations (e.g. airflow simulation, evacuation simulation). Reliable data on human movement are very scarce and can be valuable input to research in other research areas. New computer technologies allow for dynamic simulations that will provide insight into the building to be built. The research project builds upon existing methods that need to be tailored and/or extended to apply them to the building domain and to support real-time simulation.
